PGP Universal to send notification to internal sender of processing status of emails

In a setup where PGP US policy is set up so that any outgoing emails are either PGP encrypted (if the PGP US has the recipient's public pgp key) or sent via Web Messenger (if recipient's PGP pub key is not known), there is currently no facility to send a notification back to the internal sender indicating how their email has been actioned.

It would be useful if PGP US had a configuration option that allowed this to happen. Otherwise the only way senders know the email has been sent securely is either via confirming with the recipients, or bothering the PGP US administrators to go through the logs to confirm.
